gday i had the yellow top one in my last mini untill i killed it.
my stereo diddnt like it much and one day it just went capoot...
i went to get another one and my local stereo guys suggested this...
now its the same size as the optima....and just as good well mines been great so far and ive had it for 5 years now...
im currently running 2 12's and each are getting 500w a piece..plus my fronts are getting 25ow each side....and ive had no power problems....and its cheaper than the optima as well $320 including gst.....
all this stereo isnet in a mini..its in my swift so maybe the charging system is better than the minis....but there a great battery.....
do a serch on this forum as somewhere theres more infomation i posted on another post regarding the same topic and battery
